Natural killer cell T-cell lymphoma (nasal type), a rare and aggressive type of non-Hodgkin's lymphoma: Case report.

In the sinonasal tract, diffuse large B-cell lymphomas are the predominant type non-Hodgkin's lymphoma while natural killer (NK) cell T-cell lymphoma, the nasal type, constitute only 3%-12% of NHLs in this region and is the more aggressive subtype. NK cell T-cell lymphoma mostly occurs in male at the median age of 50 years and has got a poor prognosis with a 3-years overall survival (OS) of 46.3% and a 5-years OS of 42%.

Asymmetric ventriculomegaly, interhemispheric cyst, and dysgenesis of corpus callosum (AVID) - case report.

AVID (Asymmetric ventriculomegaly, interhemispheric cyst, and dysgenesis of corpus callosum) spectrum is a rare phenomenon as such in its whole and the defects are not exclusive to the condition. Each may occur in isolation or together and have characteristic clinical and imaging findings. The vast array of mimics coexisting with the condition makes it a harder diagnosis to make and requires a great length of experience and observation which may explain the limited recordings of AVID.

Hepatic portal venous gas in the case of superior mesenteric artery thrombosis in a young adult-case report.

Hepatic portal venous gas is diagnosed via computed tomography due to unusual imaging features. HPVG when linked with pneumatosis intestinalis has a high mortality rate and required urgent intervention. We present a case of a 26-year-old young adult with superior mesenteric artery thrombosis who presented with severe abdominal pain.

Non-traumatic splenic rupture and pancreatic pseudocyst as a complication of pancreatitis: A case report.

Nontraumatic splenic rupture is a rare pancreatitis complication. We present a 61-year-old chronic alcoholic male with acute on chronic pancreatitis, which progressed to pseudocyst, splenic vein thrombosis, splenic rupture, and eventually hemoperitoneum. Later, the patient required an emergency laparotomy and splenectomy.

Shepherd's crook configuration of right coronary artery and anomalous origin of left circumflex artery from right coronary cusp in a middle-aged man-A case report.

Shepherd's crook configuration of the right coronary artery is a course anomaly where the ostium is oriented superiorly with the proximal artery taking an upward turn before resuming its regular path. Although it is classified as an unimportant hemodynamic variation, it is relevant in the context of coronary artery disease due to the technical issues it causes when being treated. The anomalous origin of the left circumflex artery arising as a separate branch from the right coronary cusp is a rare variant and its significance lies in its association with sudden arrhythmia, syncope, and sudden cardiac death.

Multiple intracranial hydatid cysts in posterior fossa in an adult-A case report.

Hydatid cyst is an uncommon parasitic disease caused by larval stages of Echinococcus granulosus. The liver is the most frequently affected organ followed by the lungs and the spleen. Intracranial hydatid cysts are uncommon and occur mostly in supratentorial region.

Complete interruption of aortic arch diagnosed in adulthood: a case report.

Few patients with interrupted aortas survive into maturity, and the majority of instances are diagnosed in young children. There are only a few cases of this extremely rare total aortic interruption that survives into maturity, necessitating the substantial growth of collaterals to supply the descending aorta. Here, we describe a rare instance of an interrupted aorta in a 43-year male that presented in late adulthood with complete interruption of the aortic arch.

Dyke-Davidoff-Masson syndrome: A rare case of hemiatrophy of brain-Case report from Nepal.

Dyke-Davidoff-Masson syndrome (DDMS) is a rare neurological disorder that results from brain injury during intrauterine or early years of life. Prominent cortical sulci, dilated lateral ventricles, cerebral hemiatrophy, hyperpneumatization of the sinus, and compensatory hypertrophy of the skull are the characteristic findings. We describe a female patient who presented with a history of seizure, right-sided body weakness, and neuroimaging features of left cerebral hemiatrophy, dilatation of left lateral ventricle, left frontal sinus hyperpneumatization, asymmetric calvarial thickening, and elevation of the petrous ridge.

Role of diagnostic imaging in Rasmussen's encephalitis - A case report from .

Rasmussen's encephalitis (RE) is a relatively rare chronic inflammatory neurological disease that usually only affects one hemisphere of the brain. It primarily affects children under the age of 10, although it can also affect teens and adults, causing drug-resistant seizures, progressive hemiparesis, and dementia. RE presents as a challenging diagnosis with MRI as the cornerstone of the evaluation and nuclear imaging as a complementary tool.

Deep venous sinus thrombosis with right thalamic infarction in a young patient after COVID-19 vaccination.

Cerebral venous thrombosis is a rare illness, it compromises 0.5% of cases of cerebrovascular diseases globally. The condition can be treated if discovered and treated properly and quickly.

Clinicoradiologic diagnosis of a rare type of congenital adrenal hyperplasia: A case report from Nepal.

Congenital adrenal hyperplasia includes defects in the synthesis of steroid hormones in the adrenal cortex. The implications of this disorder manifest in other genitourinary organs, including ovaries and uterus. The diagnosis may be suspected based on the clinical and radiologic features.

Oxidative potential (OP) and mineralogy of iron ore particulate matter at the Gol-E-Gohar Mining and Industrial Facility (Iran).

Concentrations of total suspended particulate matter, particulate matter with aerodynamic diameter <2.5 μm (PM), particulate matter <10 μm (PM), and fallout dust were measured at the Iranian Gol-E-Gohar Mining and Industrial Facility. Samples were characterized in terms of mineralogy, morphology, and oxidative potential.
